Two parts, one answer

Talk like a person. Get answered like a spreadsheet.

Describe your situation however it lives in your head. The AI does the understanding; the engine does the math. Neither pretends to be the other.

01 · You
Say it in plain words.
“I’ve got $40k saved, a 6% student loan, and I’d like a house in about three years.”

No 30-field form. Type it, or use the guided inputs — your call.

Reads your words, asks only what’s missing, and later explains the why. It never guesses a number and never makes the call.

Branch, compare, undo — your original scenario always stays put.

04 · Grounded

Every comment is tied to the numbers you entered — never generic.

The AI Companion

The math tells you what. The AI tells you why.

It reads the engine’s output and explains it — never computing your outcome, never inventing a number. Two modes:

✓

Reads the engine's output for your exact scenario — no guessing.

✓

Explains the why in plain language; never invents a figure.

✓

Two modes: a structured read-out, or an open conversation.

✓

The decision always stays yours — it never makes the call.

Summary

This dual-track plan is feasible: it runs as entered, with limited cushion because payoff stretches near the horizon.

What's working

First loan cleared in month 18 — an early win on the highest-interest debt.

What to watch

Loan rate and expected return sit close together, so the margin is thin.

Methodology

Boring math, on purpose.

Deterministic and reproducible — the same inputs give the same answer, grounded in established principles rather than a rule of thumb.
